Learn the step-by-step process to charge your ASP rechargeable flashlight using a retractable micro USB charger. Keep your duty light powered and your gear organized.

Quick answer

To charge your ASP flashlight, connect the micro USB end of a retractable charger like the Retractable (Micro USB) to the flashlight’s charging port, plug the USB-A end into a power source, and let it charge until the indicator light turns solid. The retractable design keeps your cable organized and tangle-free.

Why Use a Retractable Charger for Your ASP Light?

Standard USB cables often tangle in a patrol bag or glove compartment, wasting time and creating frustration. A retractable micro USB charger solves this by ratcheting out only the length you need and rewinding neatly into a compact housing. This is especially useful for officers who need to charge a rechargeable flashlight quickly during shift changes or on the road.

Compatibility and Limitations

The Retractable (Micro USB) charger works with any ASP flashlight that has a micro USB charging port. It does not support USB-C or Lightning connectors. If your light uses a different port, you will need an adapter or a dedicated cable. The charger is designed for low-power charging; avoid using it with high-drain devices like tablets.

How to Charge Your ASP Light with a Retractable Micro USB Charger

Step 1: Locate the charging port on your ASP light: Most ASP rechargeable flashlights have a micro USB port under a rubber cover on the tail cap or body. Remove the cover gently. Don't force the cover off—use a fingernail or small tool to pry it open.
Step 2: Extend the retractable cable: Pull the micro USB end of the retractable charger to the desired length. The cord ratchets out at click-stop intervals so it stays put until you pull again to retract. Avoid yanking the cable beyond its full extension; it stops at 33 inches.
Step 3: Connect the micro USB end to your flashlight: Insert the micro USB plug firmly into the flashlight’s charging port. It should fit snugly without wobbling. If it feels loose, check that you are using the correct orientation—micro USB plugs are keyed.
Step 4: Plug the USB-A end into a power source: Connect the standard USB-A end to a USB wall charger, car adapter, or computer port. A 5V/1A adapter is ideal for safe charging. Do not use a fast-charging adapter rated above 2.1A; it may damage the flashlight battery.
Step 5: Monitor the charging status: Most ASP lights have an LED indicator that glows red while charging and turns green or blue when fully charged. Charging typically takes 2–3 hours. Unplug the cable once the light is fully charged to avoid over-discharge cycles.
Step 6: Disconnect and retract the cable: Gently pull the micro USB end outward to release the ratchet, then let the cable rewind into its housing. Replace the rubber cover on your flashlight. Always retract the cable fully before storing to prevent kinks or damage.
